Abstract |
: |
The use of intracanal medication to disinfect the root canal system has been advocated to
increase the success of root canal therapy. However, antimicrobial agents may alter the properties of
root canal dentin and consequently influence the adaptability of some root canal sealers. Thus, the
aim of this study was to evaluate the effect of calcium hydroxide paste and 2% chlorhexidine gel
when used as intracanal medications on the adaptability of resin-based (AH plus) and silicon-based
(Roekoseal) root canal sealers. The root canals of 21 extracted single rooted teeth were instrumented
using Protaper rotiUJ' system and widened to the same size. The teeth were randomly divided into
three groups; group I: no medication (control), group II: calcium hydroxide paste was used as
intracanal medi~tion for two weeks and group III: 2% chlorhexidine gel was the selected intracanal
medtcation for the same period. After 14 days, the medications were removed from the canals using
opious irrigation with distilled water. Three teeth from each group were longitudinally split and the
ntin surface was traced for elemental analysis using EDAX. The remaining teeth in each group
ubdivided into two subgroups and obturated using lateral condensation technique of gutta
1Ul. ubgroup A: obturation was done using AH plus sealer and in subgroup 8: the root canals
btu"ruted using Rokoseal sealer. The roots were then cut horizontally at the coronal, middle and
J I Jels and examined under SEM to evaluate the adaptability of the sealers to the canal walls.
Pur1hcnnore. the wettability of the sealers to medicated dentin was evaluated through measuring
the contllCt lingle. EDAX tracing revealed the presence of calcium, phosphorus and oxygen in all
samples by diffcrcill percentages; however, sodium was detected iJ40samples premedicated with 2%
chlorhcxidinc. SEM study showed that silicone based sealer had better adaptation than the resin
based one, in particular, the premedicated specimen with chlorhexidine gel. However, the statistical
analysis of contact angles of AH Plus and Roekoseal sealers to dentine surfaces before and after
application of medicaments showed insignificant difference. Thus, it was concluded that although
Ca (OH)2 and CHX, have an effect on mineral ~ontents of radicular dentine, the adaptability of the
used sealers was not significantly affected.
